Bit harsh on Jack. I'm one who thinks he has to earn his spot rather than be gifted it, and I don't think he did much wrong today. Far from our worst out there, did a few good things.
Similar with X. I thought he was one of our best today. Goldy still our best option as ruck, but good to know that X can perform if/when we need him to.
When Jack is allowed to just roam he can get involved in the play pretty well. But don't expect to win a lot of games because his opponent will be used regularly and he will make poor decisions regularly.
